According to the results of the investigation ,the geological model of the landslide is established .The landslide stability factor of safety is calculated by using limit equilibrium method first;Then,the stress field and deformation field of the landslide are simulated by using the finite difference method FLAC .Combination of the two methods can not only consider the influence of the deformation of the slope on the stability ,but also evaluate the stability of the slope with sta-bility factor of safety which is well known in geotechnical engineering .The proposed method will have broad application to the slope stability analysis .
